. This invention relates to' an improved apparatus or work table; for the repairing of radiators, the principal object of the 1mm tionbeing to provide a'table orbench so equipped that ra'diators may be handled thereon for repairingof'leak's etc, and held in anydesired position operations.

Another obj ect is to provide the table with during the repairing a water tank inwhieh a radiator may be placed,the' latter being adapted to rest on a platform in the tank arranged for vertical movement, so that a leaky radiator placed on the platform and connected to a compressed air supply maybe moved up or down to exactly determine the location of a leak therein, as indicated by the bubbles of air rising through the water.

I'have also built my improved table so as to be a complete and portable unit for repairing radiators by including all necessary devices therein, such as compressed air tanks and pumps, firepots, etc.,. control-cocks for the air and etc, sothat all that 18 necessary to place my apparatus running order when installed in a repair shop, is to connect it up with. the gas and water piping and the electric wiring of the shop. Q

At present, radiators are repaired in a very crude 'way. The leaks therein are ofttimes found by guesswork by immersing in a tank or pumping water. therethrough usually at a pointin the shop some distance from where the torches and solder potsyare kept. If necessary t o set the radiator at an 'anglein order to properly solder the same at any point, it is propped up against the columns or wall of the shop while being so soldered. These crude methods necessitate great deal of manual han- 'dling, which is not only tiring tothe' me- APPARATUS FOR: RADIATOR REPAIRING.

chanics', the radiators being somewhat heavy, but results in a slow job and great loss of time, and consequently is an item of considerable expense to the owner of the vehicle from which the radiator was taken. These disadvantages I have eliminated with the use of my improved table in which, as heretofore stated, I have arranged every thing necessary for the complete repairing of the radiator, without taking the same to any other part of the shop.

As a further object, I have produced a simple and relatively inexpensive device and "one which will give eminently satisfactory results. Y

These objects I accomplish by means of such structure and relative'arrangement of parts as will fully appear by a perusal of the following specification and cl aims.

On the drawings similar characters of reference indicate corresponding parts in the several views. V

Figure 1 is a side "elevation of my improved table.

Fig. 2 is a top plan view thereof.

Fig. 3 is a longitudinal section taken relatively on a line 3'3 of? Fig. 2.

Fig. i is a fragmentary section taken on a line 4% of Fig. 2, showing a removable radiator supporting standard.

Referring now more particularly to the numbers of reference on the drawings, the numerals 1 and 2 denote a pair of table tops of any suitable dimensions, and spaced apart 'for the positioning of a rectangular open ported on legs 5 of a suitable height. Centrally positioned in the bottom of the tank 3 andextending a suitable distance therebelow' is a cylinder or well 6 in which is adapt- .ed to slide a hollow guide or plunger 7, the same being held from turning in the well by means of a vertical lug 8 running the full height of the well and fitting into a recess 9 in the plunger 7. The same result may also be obtained by making the well and plunger square in cross section.

A drain cock?) is set in the bottom of the tank 3 to drain the same.

On the plunger is secured a vertical sleeve which supports and has secured thereto on its upper end a platform 12 01 any desired and suitable'sha'pe and construction.

Apulle'y '13 is mounted in the plunger 7 centrally thereof, the top of the plunger being' provided withislots lt therein for the passage of a cable 15 therethrough, which cable is secured to the 'topof the cylinder at one end, then passes through pulley l3 and then around pulleys 16 arranged to; carry the cable above the line of the .water in the tank 3, running thence to and being Wound around a shaft 17 secured to and extending outside the frame 4. Thesha'ft l'T is turned by means of a hand wheel 18 thereon, is adapted to be held in any desired position by.

o some such means as a pawl and ratchet 19.

Low pressure and high pressure air tanks 20 and 21 respectively are located under the table 2 and the tank 3, the high pressure tank being supplied by means of an air pump 22'driven by an electric motor The low pressure tank is filled. to a desired pressure from the high pressure tank by means of suitable piping therebctween controlledby a valve 24. Behind the tank is a .dial and control board 251 having air gages 26 thereon for the air tanks and gas andair controls 27 and-"28. respectively for blow torches29, the primaryfair control. to the valves 28 fromthe high pressure tank being had by means of 'a'valve 30. One ormore fire pots 31 are also included in the equipment," these being connected with a gas sup} ply. Positioned under the table 1 to project through the wall 4 area plurality of parallel bars 32 arranged-in staggered order. These bars are slidableoutwardly from the wallet,

7 and also pass through a guide'or supporting member 33 positioned behind tlie'front wall a and under the table 1. Stop 'lugs' 3d are provided on thebars so as to prevent them i being pulled out farther than the guide'l33.

Onlthe outer front edge of the table 1 are a plurality of vertically positioned slotted holes 35in which fit removableplns 36 secured to and BXtGllClllN down lromstandards 37.

' 7 These pins are provided with cross lugs on their lower ends, adapted to pass through the slotted holes 35. Brace brackets 39 vare mounted to the standards 37 and are adapted'to reston the table 1 to the, rear of the standards, the slotted holes 35, being posi tioned'parallel to the normal position of the brackets 39 and the-lugs 38 transversely thereof, so that when the-standards are.

placedin position, ahalf-turnis necessary tobring themtotheir normal position, and: the lugs 3Sthen rest across the narrow portion of the holes 35, thus effectually preventing the pins 36 beingforced out of the holes when aweightis thrown on the standards.

In the operation of the device, when a .leaky radiator is to be re pairechit isfir st placed on the platform 12, the tank 3 being filled with water and the platform positioned so that the radiator is entirely submerged. Air from the low pressure tank "20 is then admitted to the radiator and the general location of the leak will be evident from the resultant -bi'ibbl'es 'of air rising through the water. By then turning the hand Wheel-18to raise the platform 12, the

radiator may be gradually raised from the water till the bubbles cease, at which point in the thicknessof the radiator it is evident the'le'ak is located; "By turning the radiator by hand, this being possible by meansof the Iturnable post of the pedestal, the point of leakage may be brought within .easy reach of'the mechanid. This leak may then be soldered while still retaining the radiator on the.plat form, or itf may be taken off and placed on elther one of the tables land 2. If necessary to set the radiator at an angle for the purpose of properly soldering a leak V or otherwiseimaking repairs thereto, a couple of the bars 32 are pulled out, the great number of thesemaking t an easy matter to select any two to. give any desired angle, so

that the radiator may rest thereon,and also lean against the standards 37.

Thus, from the foregoing description it will be readilyseen that I have produced such {a device as s ibstantially fulfils V the ob ject of-the-invention as set forth herein.

While this s pecification sets forth in 'de- 7' a cure. by Letters Patent is 1. 111a work bench arran aaad equipped for the repair of radiators thereon, a plurality of independent horizontal bars slidably mounted in the side of the bench and arranged to be pulled out a redetermined distance, and removable uprig ts on the top, of the bench projecting upwardly therefrom at the edge thereof adjacent thebars.
